Fox News' Bill O'Reilly aired a truncated video clip of a statement by Mexican President Enrique Peña Nieto to claim he encourages the illegal immigration of Mexican people to the United States. But the clip left out the very next part of Peña Nieto's statement in which he noted that migratory flows from Mexico to the U.S. have fallen in part because Mexico is "opening greater opportunities for those who don't want to leave their country."
